Rattle Suppress?

[xsmokex]

Rear view mirror and trunk vibrate like crazy... doesn't sound so great.. i got two 12's in my trunk.. i know some of you guys have bigger subs than me.. how did ya get rid of the rattle? Dynomat is the obvious solution.. but do you know any others?

[HazMatt24]

there is all kinds of dynomat type stuff out there, but that is the route you're gonna need to go

[itsbmw]

I was thinking of using good stuff. because there is only one part on my trunk that rattles crazily. the part where the license plate goes, that split causes rattle.

yeah man.. you know where it says "alero" that little thin piece is what makes all the sound..

[99alerogirl]

yeah, it's really hard to stop that thing from rattling. my uncle suggested putting some clear silicone in there, but it might still rattle.

[Misuseofyou]

After fixing those rattles you'll find others. My underbody rattles, clip holding the driver's sun visor rattled, wire in my dash.. etc. I used a bunch of fatmat in the trunk, and it works well, but you'll never get rid of them all. For your rear view mirror, try tightening the screw(s); that fixed mine.

+1 thanks

For the license plate plastic part that joins with the metal part, I've heard dynomat between those two pieces fixes it. As for the mirror, tighten the screw as much as you can. I actually had my mirror fall several times before I did that and now no falling.

[AleroDrime]

um i was thinking about at thread for this but i guess it applys, im getting alot of rattling from my vents with out subs so far, usualy moving them alittle bit causes it to quit, makes it sound like busted speak sometimes, but its the vents, anyone esle have this happen and fix it?

[AleroDrime]

u guys with the rattlign lisence plates, r u using 4 screws or 2

[heineck]

use 4 and put rubber washers in between the plate and car

[AleroDrime]

i do used 4 i was gonna recommend that to them

[heineck]

yea i had mad trunk trunk rattle with the same thing 2 12's i mean its not perfect but it helps and i dont have money to drop on mat yet

[Misuseofyou]

If you wont buy matting to stop your rattles, do it for the extra base. After you do your trunk you'll find the base a lot smoother and you gain back everything that's being lost to the holes and gaps that the sound escapes through. That also means people outside the vehicle hear it less.

i used air conditioner insulation foam for the back trunk lid, just rip it to size and place pieces where the metal is contacting the plastic, you can also shove some where the rear deack meets the bottom of the back windshield to prevent that rattling, and for my rear view mirror, i dont have one and have not had it for almost 2 years because my subs just overpower it everytime.

[lonnie]

You may want to check out the dampening thread that cherrington has up and possible think about going in on a group buy with some of those guys. Its hard to get rid of all trunk rattle, very hard...the body panels on the car are actually expanding and contracting because of the pressure so just doing the trunk is going to eliminate all the rattle. I don't know what they were thinking a GM when they chose to split the trunk like that, and the license plate will rattle constantly unless you use 4 screws ...I actually use two at the top and velcroed the bottom and that has seemed to work but to each his own. Every one has a different solution and you may very well find totally different from us that works better for you.

Good Luck, and welcome to the site...I don't remember a intro thread from you!

[Gr1m]

dynomat the back of the license plate and use 4 screws works like a charm lol

[AleroDrime]

any suggestions on the rattling vents?

[Gr1m]

your talking about the front vents for heat/AC? ive never heard of them rattling

[AleroDrime]

yeah the front ones, left diver and right passenger, you move them and it usually stops, even if i put them back in the same position, but is there a way to fix it

[AleroDrime]

never mind the vents. new subs drown them out.

New PROBLEM

I can hear my trunk rattler form the outside of the car. It's not the tag.
It seems to be where the plastic meats the metal about the tag, in the separtation. If i put my fingers where the bulb is, it stops. If I push on the Alero emblem, it stops. Pressure in either direction seems like it would be effective. Any suggestions on how to acomplish this?

[jayson_waltz]

i took off that section and every spot behind it where it could contact, used put some foam weather stripping. but, this isn't a permanent fix. i had no rattles at all for a while (this was about a year ago) but now they are louder than ever. but it will hold you over til u can get mat or just do it again like i'm gonna.

[AleroDrime]

ok i kinda swear by rubber washers for quickfixes like that , will they work and how do you get it apart

any other suggestions

[AleroDrime]

is there a way somting could be wedged there that would stay and not rot or somthing

[billytheman1188]

i had rattle in that same piece..... so i bought a little bit of dynamat and put about 3 layers on the back of that piece. fixed it no problem. then i had a rattle on the top of the trunk, so i put 2 pieces under that.....FIXED. no more rattles.......this was about 2-3 years ago

[AleroDrime]

this may be retarded but is there a how too on dynomat

[MattismodderX]

^^^
www.google.com helps with questions like those

[AleroDrime]

ahh ok looked easy enough but how do i get the trunk apart to do it, remember im new

[MattismodderX]

if u just look at your trunk its pretty obvious. there are a bunch of little plastic hook looking things that unscrew for the removal of the sides. just looks for screws and whatnot. use common sense, new or not


edit: once again try google.

[fielder87]

i got iride of tat ratle,by putting in a red splinter of wood and breaking it off(lmfao).cant even notice till up close and put enough pressure of it to take away vibration.

[AleroDrime]

i saw on an older forum i guy used clear silicone, was pretty specific in an how to style, the post was maybe 3 yrs old, but i checked his thing and it said active a few days before, so i pm'd him about it to try and find out how the clear silicone has held up, anyone got an idea about it

[AleroDrime]

yeah, it's really hard to stop that thing from rattling. my uncle suggested putting some clear silicone in there, but it might still rattle.

i did this it stoped mine

now on to why i posted, i fixed that peice rattle like i said and i fixed the clips that broke on the bumper cover, now my only rattle it sthe very top of the trunk lid where it meets the glass, how do i work on this one???

What I did to my'n was use 3M double sided foamy tape.

3M VHB tape
(http://www.uline.com/Grp_240/3M-VHB-Tapes)

Just got it apart to where I could get the tape in there and stuck it on, I also used in on my plate, lol when it comes off its taking some paint.

Well what ever you do, don't do what my buddy did and just put to much door gap tape in there to make more pressure and eff up the seal.

[colonel6632]

i used those strips of foam you put around doors to seal it. put that on the bottom of the trunk panel... when i put the plastic thing on is was quite tight... rattles alot less now. For the license plate... took it off... put more of that foam around the edges and middle... used 4 screws... tightened it good... no more rattle.

and to stop the plastic thing... took off the plastic clips (they just kept snapping when i put new ones one) so took a metal washer on each side... and a spacer and tightened the shit out of them... and bam... tight connection... i can take pictures if needed... i still need to dynomat the trunk

[AleroDrime]

no all i have wrong now is the seal at the very top of the trunk, it may not be fixable

[2000aleroff]

i took the whole back of the trunk off and put this Raatmat on it(same as dynomat) but it pretty much took away almost all of the rattle from right above the licence plate. and it sounds ok.

[AleroDrime]

i got all my rattles fixed except the top of my trunk, its where the edge meets the back glass?

anyone know anything i can do?

[Randy]

i ran into the same problem as i have to 2 12's also.
for the plastic piece thats above the license plate i took it off and put a piece of hushmat (cheaper version of dynomat) on there it made a big diffrence so i would assume it would be better to put 2 strips on there.

for the license plate i also put some strips of the mat on the back with 4 screws no rattling at all.

now last but not least the trunk lid the meets with the rear window.
i once again put the mat on the inside right where it was rattling it didnt stop it completly but it did help. i only put on one piece tho, so obvliosy put more where it is needed.

you will still have rattles here and there but those are the main ones you wanna get rid of for they are the loudest.

[MattismodderX]

afugys 3m tape works like a charm. he was kind enough to let me use some to seal the two pieces together.. completely stopped the rattling. the only rattle i have now is where the back window meets the trunk and the flaps by the gas hole on the inside of the carpet

[alero_bmxer]

where the plastic part meets the metal, i took one of the licence plate light screws out and ran a long ass sheet metal screw all the way through the metal behind it an no more rattle

:lol::lol::lol::lol:

[AleroDrime]

i got mat round the lip where the trunk meets the glass, its helping but not much, someone on here has had to come up with something for it, i know theres systems on the site that hit harder then mine

[Valley olds]

Have you done anything to the part of the trunk lid between the plastic and the metal? I have seen that most of my rattling comes from there. Sound deadening material between the plastic and the metal part of the lid will really help. I know because I tried with cardboard in between just to see if it would work and it did lol

BTW I did take the cardboard out later lol

If you need more clarification on what to do, you can go ahead and ask. Ill try and explain.

[colonel6632]

i did same as vally_olds. except i put that foam that has tape on one side, the stuff that goes around doors to seal it. it worker pretty good. i put thinker foam, and tightened the plastic piece on with screws and washers instead of the plastic clips. it still rattles but not nearly as bad

hopefully that made sense
